How to unlock the Workaholic achievement in Risen - Definitive Guide
These are the skills under the Crafting tab when viewing the character sheet. Alchemy, Smithing, Prospect Ore, and Gut Animals. You need to learn all four skills, and all levels, for a total of 8 training sessions and 40 learning points - they cost 5LP each. Alchemy, Smithing and Gut Animals are easily obtained either in Harbour Town or the bandit camp. Note that you do not have to "know" all of these at the same time. You can save your game, learn a skill fully and then reload your previous save to keep your LP for something more useful.
In chapter 1 only Olf, one of the three treasure hunters in Harbour Town, will teach you Prospecting and it requires the completion of two key quests so the Order will release him from prison. The first is the Don's amulet, hidden in a secret room in his old mansion. It doesn't matter if you do this for the Order or the Bandits. The next is the three golden bowls - the quest you receive from the Order guard outside the Warehouse. Two of the triplets have one bowl each, and the last is hidden in the lighthouse on the upper floor, and requires a Telekinesis spell to reach (which Jack the lighthouse keeper sells). Once both those quests are complete and the respective parties have been informed of the outcome, talk to the guard outside the Don's old mansion, and Olf will be released shortly.
